API Gateway

Managed API routing for third-party services, provided by Maton. Use this only for a user-requested app, account, and task.

Quick Start

CLI:

maton slack channel list --types public_channel --limit 10

maton api '/slack/api/conversations.list?types=public_channel&limit=10'

Python:

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/slack/api/conversations.list?types=public_channel&limit=10')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Routing

Use https://api.maton.ai/ with the app-prefixed routes documented in the examples below or in the matching reference file.

Usage protocol:

1. Only invoke after the user specifies the exact app, account, and task.
2. Always start with read-only (GET) calls to verify the target account, resource identifiers, and current state.
3. All non-GET requests are denied unless the user explicitly approves each one. Before any POST, PUT, PATCH, or DELETE call, present the user with: the exact connection ID, the full endpoint path, the request body, and the expected outcome — then wait for approval.
4. If the user's request implies a non-GET operation, first show them what you intend to call and ask for confirmation. Do not infer approval from the original request.

Read-only route examples:

https://api.maton.ai/slack/api/conversations.list?types=public_channel&limit=10
https://api.maton.ai/google-mail/gmail/v1/users/me/messages

The first path segment is the app identifier listed in Supported Services. For Gmail, use /google-mail/gmail/v1/users/me/messages.

Installation

NPM:

npm install -g @maton-ai/cli

Homebrew:

brew install maton-ai/cli/maton

Authentication

IMPORTANT — Credential Safety:

• Treat MATON_API_KEY as a secret. Never log it, echo it, paste it into prompts, or expose it in shared files, command output, or tool results.
• Connection creation requires explicit user approval. Before creating any connection, ask the user to confirm the specific service and confirm they intend to authorize access. Never create connections on the agent's own initiative.
• Least-privilege scopes: When a service offers scope selection during OAuth, select only the scopes the current task requires. Do not accept broader scopes for convenience.
• Remove connections immediately after the task is complete if they are no longer needed (maton connection delete {id}).
• If the key may have been exposed (logs, screenshots, shared terminals), rotate it immediately at maton.ai/settings.
• Never share the key across users, workflows, or environments that do not require it.

CLI:

maton login                          # Opens browser for API key
maton login --interactive            # Skip browser, paste API key directly
maton whoami                         # Show current auth state

Manual:

1. Sign in or create an account at maton.ai
2. Go to maton.ai/settings
3. Click the copy button on the right side of API Key section to copy it
4. Set your API key as MATON_API_KEY:

export MATON_API_KEY="YOUR_API_KEY"

Connection Management

Connection management uses a separate base URL: https://api.maton.ai

List Connections

CLI:

maton connection list slack --status ACTIVE

maton api -X GET /connections -f app=slack -f status=ACTIVE

Python:

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/connections?app=slack&status=ACTIVE')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Query Parameters (optional):

• app - Filter by service name (e.g., slack, hubspot, salesforce)
• status - Filter by connection status (ACTIVE, PENDING, FAILED)

Response:

{
  "connections": [
    {
      "connection_id": "{connection_id}",
      "status": "ACTIVE",
      "creation_time": "2025-12-08T07:20:53.488460Z",
      "last_updated_time": "2026-01-31T20:03:32.593153Z",
      "url": "https://connect.maton.ai/?session_token=5e9...",
      "app": "slack",
      "method": "OAUTH2",
      "metadata": {}
    }
  ]
}

Create Connection

CLI:

maton connection create slack

maton api /connections -f app=slack

Python:

python <<'EOF'
import urllib.request, os, json
data = json.dumps({'app': 'slack'}).encode()
req = urllib.request.Request('https://api.maton.ai/connections', data=data, method='POST')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Content-Type', 'application/json')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Request Body:

• app (required) - Service name (e.g., slack, notion)
• method (optional) - Connection method (API_KEY, BASIC, OAUTH1, OAUTH2, MCP)

Get Connection

CLI:

maton connection view {connection_id}

maton api /connections/{connection_id}

Python:

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/connections/{connection_id}')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Response:

{
  "connection": {
    "connection_id": "{connection_id}",
    "status": "ACTIVE",
    "creation_time": "2025-12-08T07:20:53.488460Z",
    "last_updated_time": "2026-01-31T20:03:32.593153Z",
    "url": "https://connect.maton.ai/?session_token=5e9...",
    "app": "slack",
    "metadata": {}
  }
}

Open the returned URL in a browser to complete service authorization.

Delete Connection

CLI:

maton connection delete {connection_id}

maton api -X DELETE /connections/{connection_id}

Python:

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/connections/{connection_id}', method='DELETE')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Specifying Connection

If you have multiple connections for the same app, specify which connection to use:

CLI:

maton slack channel list --types public_channel --limit 10 --connection {connection_id}

maton api '/slack/api/conversations.list?types=public_channel&limit=10' --connection {connection_id}

Python:

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/slack/api/conversations.list?types=public_channel&limit=10')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Maton-Connection', '{connection_id}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

If you have multiple connections, always specify the connection to ensure requests go to the intended account.

Security & Permissions

• Access is scoped to the specific third-party service connected through each Maton connection and the scopes the user authorized.
• Use least privilege. Connect only the services needed for the current task. Prefer read-only scopes and revoke unused connections promptly.
• Default to read/list calls. Retrieve or list resources first to verify identifiers, account context, and current state before proposing any change.
• All operations that modify data require explicit user approval. Before executing any POST, PUT, PATCH, or DELETE call, confirm the target service, resource, payload, and intended effect wit
